Has anybody got upset with you because you’re sick?

A lot of people at my job is getting sick and allergies. My dad and his gf told me I need to protect myself at all times which is true and hope I feel better. I warned my older brother that I’m not feeling well and must of caught it and he didn’t look happy. I mean you can’t blame him. He said it’s the damn sickness that’s going on and I think he’s very upset with me for being sick.
Not everyone got sick but it’s going around and i some parents send they’re kids sick which pisses me off but still can’t blame them. I’m upset right now because my brother is upset. I think he’s upset with me. I think he’s upset over the sickness going.
It would have been worse if I didn’t tell him I’m unwell.
I don’t know why I’m crying. I need to buck up. I need to protect myself.
